Abstract:
An embodiment of an electrochemical energy storage device has been disclosed. The device includes a housing, an electrolyte contained within the housing, and an electrode arrangement at least partially submerged in the electrolyte. The housing has an interior surface coated in an activated carbon material. Methods of fabrication are also described.
Abstract:
Electrochemical energy storage devices such as electric double layer capacitors include flexible metal contact current collectors establishing electrical contact with a conductive housing and a conductive cover. The flexible current collector simplifies manufacturing of the device and avoids laser welding on the conductive housing. The manufacture devices are operable with a reduced direct current resistance by virtue of the flexible current collector.
